Description
Demonstration of Biot-Savart law .A wire carrying electric current generates magnetic field around it. For a long straight wire the magnetic field lines form circles around the wire, as it follows from the Biot-Savart law. The magnetic field lines are visualized here by placing small compasses around a wire. When the current is not flowing, the needles point to the Earth's magnetic North. When the current is flowing, the needles follow a circle around the wire (as shown in this photograph). Photo 2 of 2.
